When I used a batch operation to extract function keywords from the document. Comparing the API on the wiki, I found that there was something wrong with the brackets in the sspr and rawequal in the document:

    SSPR(SX, SY, SW, SH, DX, DY, [DW, DH], [FLIP_X], [FLIP_Y]]

Does it should be like:

    SSPR(SX, SY, SW, SH, DX, DY, [DW, DH], [FLIP_X], [FLIP_Y])

and

    RAWEQUAL(TBL1,TBL2

shoud be like:

    RAWEQUAL(TBL1,TBL2)

?
